In order to promote pharmaceutical research within the European Community and to keep the pharmaceutical industry from relocating to countries which offer better protection, EC Regulation Number 1768/92 for supplementary protection certificates (SPCs) was created. SPCs in the Netherlands are also governed by Regulation Number 1768/92. This is a clear and simple regulation which was meant to extend the life of a patent as far as it covered a medicinal product which had received regulatory approval and which should have led to harmonized SPC legislation in the European Community.
